Israeli Prime Minister Benjamin Netanyahu said Sunday that his country had dealt "severe blows" to Iranian and Syrian forces inside Syria and would continue to combat any further aggression.

Saturday's raids came after Syrian air defenses shot down an Israeli F-16 fighter with anti-aircraft fire, the first time Israel has lost a warplane in battle since 1982.

The Israeli pilots were able to eject from their aircraft, which crashed in Israel, according to the Israeli military. Israel said one of its pilots was "severely injured" in the "emergency evacuation," while another pilot was slightly injured.

Israel said it hit a dozen Iranian and Syrian targets in Syria, including command centers and missile defenses. Earlier, Israel said it had shot down an Iranian drone launched from Syria after it entered Israeli territory late Friday.

Several Israeli officials said they refused to accept an Iranian military presence in Syria, which Tehran denies exists.
